[0052] The present utility model will be described in detail below in conjunction with the specific implementation manners shown in the accompanying drawings. However, these implementation manners do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation manners is included within the protection scope of the present utility model.

[0053] In conjunction with Figures 1 to 4 , an implementation manner of the present utility model provides a dental system 100.

[0054] The dental system 100 includes a force application platform 10 having a first action point A1, a second action point A2 spaced apart from the force application platform 10, and a connecting member 20 connecting the first action point A1 and the second action point A2.

[0055] When the dental system 100 is worn in the oral cavity, the upper teeth T1 and the lower teeth T2 clamp the force application platform 10, the second action point A2 directly or indirectly contacts the teeth, and the connecting member 20 generates a force between the first action point A1 and the second action point A2.

[0056] When the connecting member 20 generates a force between the first action point A1 and the second action point A2, the force can be transmitted to the teeth through the second action point A2 to achieve tooth orthodontics, such as molar distal movement, tooth intrusion or extrusion, tooth rotation, etc., and at this time, the force application platform 10 can be used as an anchorage to provide the force.

[0057] The force - applying platform 10 of this embodiment is clamped between the upper teeth T1 and the lower teeth T2, which will not bring additional discomfort to the patient. At this time, the position of the force - applying platform 10 in the oral cavity is stable, which can effectively increase the anchorage and provide a stable acting force.

[0058] The structure of the force - applying platform 10 can be in various forms, including:

[0059] Combined with Figures 1 to 4 , in the first form, the force - applying platform 10 includes two shell - like bodies 11 and 12 connected to each other. When the dental system 100 is worn in the oral cavity, the two shell - like bodies 11 and 12 are respectively sleeved on the upper teeth T1 and the lower teeth T2.

[0060] Taking the two shell - like bodies 11 and 12 as the first shell - like body 11 sleeved on the upper teeth T1 and the second shell - like body 12 sleeved on the lower teeth T2 respectively, the upper teeth T1 support the first shell - like body 11, the lower teeth T2 support the second shell - like body 12, and the first shell - like body 11 and the second shell - like body 12 are connected to each other. At this time, the force - applying platform 10 wraps the upper teeth T1 and the lower teeth T2, and the force - applying platform 10 is stably fixed in the oral cavity by the common support of the upper teeth T1 and the lower teeth T2.

[0061] "The force - applying platform 10 wraps the upper teeth T1 and the lower teeth T2" means that the force - applying platform 10 extends to the buccal surface and / or lingual surface of the teeth. The force - applying platform 10 can directly or indirectly contact the buccal surface and / or lingual surface of the teeth. The same applies hereinafter.

[0062] Optionally, the force - applying platform 10 includes a retention structure connecting the two shell - like bodies 11 and 12, and the retention structure restricts the relative movement of the two shell - like bodies 11 and 12.

[0063] The retention structure can be at least one of a mechanical retention structure, an adhesive retention structure, a welding retention structure, and a magnetic retention structure. A mechanical retention structure refers to a structure that realizes mutual limiting through the mutual cooperation of physical structures, such as concave - convex fitting, clamping, embedding, sleeving, riveting, etc.

[0064] The retention structure can be arranged at the two occlusal surfaces where the two shell - like bodies 11 and 12 are oppositely arranged, and / or in the areas corresponding to the buccal surface or lingual surface of the teeth of the two shell - like bodies 11 and 12.

[0065] The degree of freedom of the relative movement of the two shell - like bodies 11 and 12 restricted by the retention structure is zero, that is, the retention structure can restrict all - dimensional relative movement and relative rotation between the two shell - like bodies 11 and 12, which can improve the overall stability of the force - applying platform 10, but not limited thereto. The retention structure can also restrict the relative movement of some dimensions of the two shell - like bodies 11 and 12.

[0066] Combined with Figure 5 and Figure 6 In the second form, the force - applying platform 10a includes a shell - like body 11a. When the dental system 100a is worn in the oral cavity, one of the upper teeth T1 and the lower teeth T2 wears the shell - like body 11a, and the other occludes with the shell - like body 11a.

[0067] Taking the case where the shell - like body 11a is sleeved on the upper teeth T1 as an example, the upper teeth T1 support the shell - like body 11a, and the occlusal surface of the lower teeth T2 occludes with the shell - like body 11a. At this time, the force - applying platform 10a wraps the upper teeth T1 but does not wrap the lower teeth T2. The force - applying platform 10a is stably fixed in the oral cavity by the support of the upper teeth T1 and the occlusion of the lower teeth T2.

[0068] In order to improve the cooperation stability between the lower teeth T2 and the force - applying platform 10a, a retention structure, such as a concave - convex mating structure, etc., can be added between the lower teeth T2 and the force - applying platform 10a.

[0069] Combined with Figure 7 and Figure 8 In the third form, the force - applying platform 10b is an intermediate structure. When the dental system 100b is worn in the oral cavity, the intermediate structure is located in the space formed by the upper occlusal surface of the upper teeth T1 and the lower occlusal surface of the lower teeth T2.

[0070] The force - applying platform 10b is located in the space formed by the upper occlusal surface and the lower occlusal surface, that is, the force - applying platform 10b does not wrap the upper teeth T1 and the lower teeth T2. The force - applying platform 10b is stably fixed in the oral cavity by the common occlusion of the upper teeth T1 and the lower teeth T2.

[0071] In order to improve the cooperation stability between the upper teeth T1, the lower teeth T2 and the force - applying platform 10b, a retention structure, such as a concave - convex mating structure, etc., can be added between the upper teeth T1 and the force - applying platform 10b and between the lower teeth T2 and the force - applying platform 10b.

[0072] Optionally, in the first form and the second form with the shell - like body above, taking the first shell - like body 11 of the first form as an example, the first shell - like body 11 includes an extension part 111 (see Figure 10 ) extending to the gingival area. The first action point A1 is located at the extension part 111. In this way, the setting area of the first action point A1 can be increased to provide the acting force more effectively.

[0073] The first shell - like body 11 includes a shell - like main body and a flexible structure on the inner wall of the shell - like main body. When the first shell - like body 11 is worn on the teeth, through the extrusion deformation of the flexible structure, it can better adapt to the patient's dentition and can also fix the force - applying platform 10 more stably in the oral cavity.

[0074] The flexible structure and the inner wall can be combined together by means of adhesion, welding, fusion welding, etc.

[0075] The corresponding part of the first housing 11 is provided corresponding to some or all of the single-jaw teeth, that is, the first housing 11 can wrap a partial area of the upper jaw teeth T1, or the first housing 11 can wrap all of the upper jaw teeth T1, which can be determined according to the actual situation.

[0076] The first housing 11 has an opening 112. When the dental system 100 is worn in the oral cavity, the opening 112 exposes the second acting point A2, and the connecting member 20 can contact the second acting point A2 through the opening 112 and apply a force to the second acting point A2.

[0077] When the first housing 11 wraps a partial area of the upper jaw teeth T1, the area of the upper jaw teeth T1 not wrapped by the first housing 11 can be regarded as the opening 112.

[0078] For the description of the second housing 12 in the first form and the housing 11a in the second form, reference can be made to the description of the foregoing first housing 11, and details will not be repeated here.

[0079] There are various examples of the cooperation form between the force application platform and the teeth.

[0080] In the first example, combined Figures 1 to 4 , the force application platform is the force application platform 10 in the foregoing first form, that is, the force application platform 10 includes two housings 11 and 12, and the force application platform 10 cooperates with the teeth without wearing any orthodontic components.

[0081] Each of the housings 11 and 12 has a cavity matching the teeth. When the dental system 100 is worn in the oral cavity, the inner wall of each cavity directly contacts the teeth, and the "inner wall of the cavity" is the solid structure surrounding and forming the cavity.

[0082] Here, when the housings 11 and 12 include flexible structures, the cavity is the space surrounded by the flexible structures, that is, when the dental system 100 is worn in the oral cavity, the flexible structures directly contact the teeth.

[0083] Specifically, the first housing 11 has a first cavity S1 matching the upper jaw teeth T1, and the second housing 12 has a second cavity S2 matching the lower jaw teeth T2. When the dental system 100 is worn in the oral cavity, the first cavity S1 wraps the upper jaw teeth T1, and the inner wall of the first cavity S1 directly contacts the teeth. The second cavity S2 wraps the lower jaw teeth T2, and the inner wall of the second cavity S2 directly contacts the teeth.

[0084] The first cavity S1 has a designed amount for orthodontic tooth treatment. When the first shell 11 is worn on the upper teeth T1, this designed amount can achieve the movement, rotation, etc. of the upper teeth T1. That is, at this time, in addition to serving as an anchorage, the first shell 11 itself can also play an orthodontic role, but not limited to this. The first cavity S1 may also have no designed amount.

[0085] For the description of the second cavity S2, reference can be made to the first cavity S1, and details will not be repeated here.

[0086] An opening 112 can be formed at the first shell 11. The opening 112 exposes the tooth surface. The second acting point A2 is located on the tooth surface, that is, at this time, the second acting point A2 directly contacts the tooth. The opening can also be provided at the second shell 12.

[0087] In this example, the first shell 11 and the second shell 12 of the present example directly cooperate with the teeth. The first shell 11 and the second shell 12 can be stably fitted to the teeth, greatly improving the stability of the entire force application platform 10 fixed in the oral cavity.

[0088] In other embodiments, it can also be the force application platform 10a of the aforementioned second form or the force application platform 10b of the third form that cooperate with the teeth without wearing any orthodontic components.

[0089] In the second example, the force application platform is the force application platform 10 of the aforementioned first form, that is, the force application platform 10 includes two shells 11 and 12, and the force application platform 10 cooperates with the teeth wearing orthodontic brackets.

[0090] In this example, all or part of the tooth surface has orthodontic brackets. The second acting point A2 is located at the orthodontic brackets on the tooth surface, that is, the second acting point A2 indirectly contacts the tooth, or the second acting point A2 bypasses the orthodontic brackets and is directly located on the tooth surface, that is, the second acting point A2 directly contacts the tooth.

[0091] Optionally, openings can be formed at the shells 11 and 12 to expose some orthodontic brackets. The exposed orthodontic brackets can generate the second acting point A2. The areas of the shells 11 and 12 that do not correspond to the orthodontic brackets can directly contact the teeth to improve the stability of the cooperation between the shells 11 and 12 and the teeth, but not limited to this.

[0092] In other embodiments, it can also be the force application platform 10a of the aforementioned second form or the force application platform 10b of the third form that cooperate with the teeth wearing orthodontic brackets.

[0093] In the third example, in combination Figure 9, the force - applying platform is the force - applying platform 10 of the first form described above, that is, the force - applying platform 10 includes two shell - like bodies 11, 12, and the force - applying platform 10 cooperates with the teeth wearing the invisible orthodontic appliance 30.

[0094] The dental system 100 further includes at least one invisible orthodontic appliance 30. When the dental system 100 is worn in the oral cavity, each invisible orthodontic appliance 30 is sleeved on the teeth of a single jaw, and the shell - like bodies 11, 12 are sleeved on the side of the invisible orthodontic appliance 30 away from the teeth.

[0095] The invisible orthodontic appliance 30 has a designed amount for orthodontic treatment. When the invisible orthodontic appliance 30 is worn at the teeth of a single jaw (the upper - jaw teeth T1 or the lower - jaw teeth T2), this designed amount can achieve tooth movement, rotation, etc.

[0096] The invisible orthodontic appliance 30 is worn at the teeth of a single jaw. The shell - like bodies 11, 12 have cavities, and the shell - like bodies 11, 12 are fitted to the outer side of the invisible orthodontic appliance 30 through the cavities. At this time, the shell - like bodies 11, 12 indirectly contact the teeth of a single jaw through the invisible orthodontic appliance 30.

[0097] Optionally, the dental system 100 may include two invisible orthodontic appliances 30 that respectively cooperate with the upper - jaw teeth T1 and the lower - jaw teeth T2, and the two shell - like bodies 11, 12 are respectively sleeved on the outer sides of the two invisible orthodontic appliances 30. Or, the dental system 100 only includes one invisible orthodontic appliance 30, and one of the two shell - like bodies 11, 12 is sleeved on the outer side of the invisible orthodontic appliance 30, and the other is directly sleeved on the teeth.

[0098] The shell - like bodies 11, 12 may be completely matched with the corresponding invisible orthodontic appliance 30. Or, there are differences between the shell - like bodies 11, 12 and the corresponding invisible orthodontic appliance 30. It only needs to ensure that there is a certain limiting effect between the shell - like bodies 11, 12 and the invisible orthodontic appliance 30. At this time, the shell - like bodies 11, 12 can be stably fixed in the oral cavity through the invisible orthodontic appliance 30 and the upper and lower jaw teeth T2.

[0099] When the second action point A2 is located on the side with the invisible orthodontic appliance 30, the second action point A2 is located on the surface of the invisible orthodontic appliance 30 away from the teeth, that is, the second action point A2 indirectly contacts the teeth.

[0100] Optionally, windows may be formed on the shell - like bodies 11, 12 to expose part of the invisible orthodontic appliance 30, and the exposed invisible orthodontic appliance 30 can generate the second action point A2.

[0101] In other embodiments, it may also be the force - applying platform 10a of the second form or the force - applying platform 10b of the third form described above that cooperate with the teeth wearing the invisible orthodontic appliance 30.

[0102] Optionally, in combination with Figures 1 to 4, the connecting member 20 includes a base 21 fixed to the first acting point A1, a mounting seat 22 fixed to the second acting point A2, and an intermediate member 23 connecting the base 21 and the mounting seat 22. The intermediate member 23 is elastically or rigidly connected to the base 21, and the intermediate member 23 is elastically or rigidly connected to the mounting seat 22.

[0103] "The intermediate member 23 is elastically connected to the base 21" may mean that at least one of the intermediate member 23 and the base 21 is a deformable elastic structure, and "the intermediate member 23 is rigidly connected to the base 21" may mean that both the intermediate member 23 and the base 21 are non-deformable structures.

[0104] Similarly, "the intermediate member 23 is elastically connected to the mounting seat 22" may mean that at least one of the intermediate member 23 and the mounting seat 22 is a deformable elastic structure, and "the intermediate member 23 is rigidly connected to the mounting seat 22" may mean that both the intermediate member 23 and the mounting seat 22 are non-deformable structures.

[0105] The acting force generated by the connecting member 20 is transmitted between the first acting point A1 and the intermediate member 23 through the base 21, and is transmitted between the second acting point A2 and the intermediate member 23 through the mounting seat 22, which facilitates the installation of the connecting member 20 and can control the stable transmission of the acting force.

[0106] The acting force generated by the connecting member 20 finally acts on the second acting point A2 to realize tooth correction. The acting force received by the second acting point A2 may include a pulling force away from the second acting point A2 and a pushing force towards the second acting point A2. Both the pulling force and the pushing force can be added to the second acting point A2 through the mounting seat 22.

[0107] In other embodiments, the base 21 or the mounting seat 22 may also be cancelled, and the acting force may be directly transmitted at the first acting point A1 or the second acting point A2.

[0108] For example, the mounting seat 22 is cancelled, so that the connecting member 20 directly acts on the second acting point A2.

[0109] The connecting member 20 is a rigid structure connecting the second acting point A2. The acting force generated by the connecting member 20 is directed towards the second acting point A2, that is, the acting force generated by the connecting member 20 is a pushing force, and the connecting member 20 pushes the second acting point A2 to realize tooth correction.

[0110] Specifically, the connecting member 20 may be a rigid arch wire. One end of the rigid arch wire directly abuts against the second acting point A2 to apply a force to the tooth. When the second acting point A2 directly contacts the tooth, the second acting point A2 may be a point on the tooth surface, and the connecting member 20 directly abuts against this point to apply a force to the tooth.

[0111] Optionally, the base 21 is a hook-shaped structure, a buckle-shaped structure, a shell body with a slot, a tubular structure or a groove-shaped structure, the mounting seat 22 is a hook-shaped structure, a buckle-shaped structure, an orthodontic appliance with a slot, a tubular structure or a groove-shaped structure, and the middle member 23 is an annular elastic member or a rigid arch wire.

[0112] Here, "shell body with a slot" means that when the force application platform has a shell body, a slot structure formed by cutting a part of the shell body, and the slot structure can be set corresponding to the teeth, or the slot structure corresponds to the gingiva; "orthodontic appliance with a slot" means that when the dental system has an invisible orthodontic appliance 30, a slot structure formed by cutting a part of the invisible orthodontic appliance 30, and the slot structure can be set corresponding to the teeth, or the slot structure corresponds to the gingiva.

[0113] The connection between the base 21 and the middle member 23 is a fixed connection or a detachable connection, and the connection between the mounting seat 22 and the middle member 23 is a fixed connection or a detachable connection.

[0114] The base 21 and the force application platform 10 are integrally formed, or the base 21 and the force application platform 10 are connected by means of snap connection, bonding, welding or riveting.

[0115] Optionally, the base 21 and the mounting seat 22 connected by the same middle member 23 are located in the same jaw, that is, the base 21 and the mounting seat 22 at both ends of the same middle member 23 are simultaneously set corresponding to the upper jaw or simultaneously set corresponding to the lower jaw.

[0116] And / or the base 21 and the mounting seat 22 connected by the same middle member 23 are located in different jaws, that is, one of the base 21 and the mounting seat 22 at both ends of the same middle member 23 corresponds to the upper jaw and the other corresponds to the lower jaw, and specifically can be determined according to the position of the teeth to be corrected, the direction and magnitude of the required acting force, etc.

[0117] Optionally, the base 21 is set corresponding to the lingual side or the buccal side of the force application platform 10, and the mounting seat 22 is set corresponding to the buccal side or the lingual side of the teeth.

[0118] The base 21 and the mounting seat 22 can be simultaneously located on the buccal side of the teeth, and the middle member 23 connecting the base 21 and the mounting seat 22 is also located on the buccal side of the teeth; or, the base 21 and the mounting seat 22 can be simultaneously located on the lingual side of the teeth, and the middle member 23 connecting the base 21 and the mounting seat 22 is also located on the lingual side of the teeth; or, one of the base 21 and the mounting seat 22 is located on the lingual side of the teeth and the other is located on the buccal side of the teeth, and the middle member 23 passes through the occlusal surface of the teeth to connect the base 21 and the mounting seat 22.

[0119] Optionally, the one-to-one matching is not limited among the base 21, the mounting seat 22 and the middle member 23.

[0120] For example, the dental system 100 includes a base 21 and a plurality of mounting seats 22. One end of a plurality of middle pieces 23 is respectively connected to the plurality of mounting seats 22, and the other ends of the plurality of middle pieces 23 are all connected to a base 21, that is, one base 21 cooperates with the plurality of mounting seats 22.

[0121] Alternatively, the dental system 100 includes a mounting seat 22 and a plurality of bases 21. One end of a plurality of middle pieces 23 is respectively connected to the plurality of bases 21, and the other ends of the plurality of middle pieces 23 are all connected to a mounting seat 22, that is, one mounting seat 22 cooperates with the plurality of bases 21.

[0122] Combined with Figures 1 to 4 , specific embodiments of the dental system 100 are introduced.

[0123] In this specific embodiment, the dental system 100 is used in the oral cavity. The dental system 100 includes a force application platform 10 and a connecting member 20. The force application platform 10 includes two shell bodies 11, 12 that are connected to each other and respectively cooperate with the upper teeth T1 and the lower teeth T2. The connecting member 20 includes a mounting seat 22 independent of the force application platform 10, a base 21 located on the force application platform 10, and a middle piece 23 connecting the mounting seat 22 and the base 21.

[0124] When the dental system 100 is worn in the oral cavity, the force application platform 10 is sleeved on the upper teeth T1 and the lower teeth T2 through the two shell bodies 11, 12. The mounting seat 22 independent of the force application platform 10 directly or indirectly contacts the teeth. The middle piece 23 generates a force between the base 21 and the mounting seat 22. This force can be directly or indirectly transmitted to the teeth through the mounting seat 22 to achieve tooth correction, such as distal movement of molars, intrusion or extrusion of teeth, tooth rotation, etc. At this time, the force application platform 10 can be used as an anchorage to provide the force.

[0125] In this embodiment, the force application platform 10 of the present embodiment is sleeved on the upper teeth T1 and the lower teeth T2 through the two connected shell bodies 11, 12, which will not bring additional discomfort to the patient. Moreover, the upper teeth T1 and the lower teeth T2 support the force application platform 10 at the same time, and the force application platform 10 can be stably fixed in the oral cavity. The force application platform 10 can provide a stable force as an anchorage for tooth correction.

[0126] One of the two shell bodies 11, 12 matches all the upper teeth T1, and the other matches all the lower teeth T2.

[0127] Here, taking two shell bodies 11 and 12 as an example of the first shell body 11 and the second shell body 12, the first shell body 11 has a first cavity S1 that matches all the upper teeth T1, and the second shell body 12 has a second cavity S2 that matches all the lower teeth T2. When the dental system 100 is worn in the oral cavity, the first cavity S1 wraps all the upper teeth T1, and the second cavity S2 wraps all the lower teeth T2, which can greatly improve the stability of the force application platform 10 fixed in the oral cavity.

[0128] A flexible structure can be arranged inside the first cavity S1 and the second cavity S2 to increase the stability of the cooperation between the two shell bodies 11 and 12 and the teeth, and further improve the stability of the force application platform 10 fixed in the oral cavity.

[0129] The first shell body 11 includes an extension part 111 extending to the gingival area, and the base 21 is located at the extension part 111. In this way, the setting area of the base 21 can be increased, and the lever arm of the required acting force can be maximized within the limited setting area of the first shell body 11, thereby effectively increasing the required acting force.

[0130] The first shell body 11 includes a window 112. When the dental system 100 is worn in the oral cavity, the mounting seat 22 is connected to the teeth at the window 112, that is, the window 112 can be used to expose the mounting seat 22.

[0131] The description of the second shell body 12 can refer to the first shell body 11 and will not be elaborated here. The extension part and the window can be arranged at the first shell body 11 and / or the second shell body 12 as needed.

[0132] Optionally, one of the base 21 and the mounting seat 22 corresponds to the upper teeth T1, and the other corresponds to the lower teeth T2. Or, both the base 21 and the mounting seat 22 correspond to the upper teeth T1. Or, both the base 21 and the mounting seat 22 correspond to the lower teeth T2. That is, the base 21 and the mounting seat 22 can be arranged on the same jaw, or the base 21 and the mounting seat 22 can be arranged on different jaws.

[0133] Both the base 21 and the mounting seat 22 are arranged corresponding to the buccal side of the teeth, which is convenient for the connection between the middle piece 23 and the base 21 and the mounting seat 22.

[0134] Next, several specific application scenarios of the dental system 100 will be introduced.

[0135] Combined with Figures 1 to 4 , it is an application scenario for tooth elongation correction.

[0136] The force application platform 10 includes two housing bodies 11 and 12 that are connected to each other. The two housing bodies 11 and 12 include a first housing body 11 and a second housing body 12. The first housing body 11 includes a window 112. The base 21 is located in the second housing body 12. When the dental system 100 is worn in the oral cavity, the mounting seat 22 is directly connected to the tooth at the window 112, and the middle member 23 extends substantially along the gingival occlusal plane direction z.

[0137] Both the base 21 and the mounting seat 22 are provided corresponding to the buccal side of the tooth. Both the base 21 and the mounting seat 22 are buckle-shaped structures. The middle member 23 is an annular elastic member, that is, there is an elastic connection between the middle member 23 and the base 21, and there is an elastic connection between the middle member 23 and the mounting seat 22. The base 21 is bonded to the force application platform 10, and the mounting seat 22 is bonded to the tooth.

[0138] When the dental system 100 is worn in the oral cavity, the middle member 23 deforms to generate a pulling force F that is away from the mounting seat 22 and substantially parallel to the gingival occlusal plane direction z. This pulling force F acts on the tooth through the mounting seat 22, thereby realizing the elongation correction of the tooth.

[0139] In other embodiments, the extending direction of the middle member 23 may have an acute angle with the gingival occlusal plane direction z. At this time, the component force of the force generated by the middle member 23 along the gingival occlusal plane direction z can be used as the pulling force for elongation correction.

[0140] When the force applied by the middle member 23 to the mounting seat 22 is a pushing force, the intrusion correction of the tooth can be realized.

[0141] Combined Figures 10 to 12 , it is an application scenario for tooth intrusion correction.

[0142] The force application platform 10c includes two housing bodies 11c and 12c that are connected to each other. The two housing bodies 11c and 12c include a first housing body 11c and a second housing body 12c. The first housing body 11c includes a window 112c. The connecting member 20c includes two bases 21c located on the mesial side and the distal side of the window 112c.

[0143] When the dental system 100c is worn in the oral cavity, the mounting seat 22c is directly connected to the tooth at the window 112c. The two bases 21c are located in the first housing body 11c. The two bases 21c are farther from the second housing body 12c than the mounting seat 22c, and the two middle members 23c are respectively connected to the two bases 21c and are simultaneously connected to the mounting seat 22c.

[0144] Both the two bases 21c and the mounting seat 22c are provided corresponding to the buccal side of the tooth. A substantially "V" shape is formed among the two bases 21c, the two middle members 23c, and one mounting seat 22c.

[0145] Both the base 21c and the mounting seat 22c are buckle-shaped structures, and the middle member 23c is an annular elastic member. That is, there is an elastic connection between the middle member 23c and the base 21c, and an elastic connection between the middle member 23c and the mounting seat 22c. The two bases 21c are bonded to the force application platform 10c, and the mounting seat 22c is bonded to the tooth.

[0146] When the dental system 100c is worn in the oral cavity, the two middle members 23c are deformed to generate a first pulling force F1 and a second pulling force F2 that are inclined with respect to the gingival occlusal surface direction z. The first pulling force F1 and the second pulling force F2 act on the tooth through the mounting seat 22c, thereby realizing the intrusion correction of the tooth.

[0147] Specifically, the first pulling force F1 includes a first component force F11 extending along the gingival occlusal surface direction z, and the second pulling force F2 includes a second component force F21 extending along the gingival occlusal surface direction z. The first component force F11 and the second component force F21 act to intrude the tooth.

[0148] The first housing 11c includes an extension 111c extending to the gingival area. Here, taking two extensions 111c as an example, the two bases 21c are respectively located at the two extensions 111c. At this time, when the magnitudes of the pulling force F1 and the second pulling force F2 remain unchanged, the lever arms corresponding to the first component force F11 and the second component force F21 increase, thereby effectively increasing the first component force F11 and the second component force F21, that is, enhancing the intrusion effect on the tooth.

[0149] In other embodiments, the position of the mounting seat remains unchanged, and the two bases can be moved downward to the second housing 12c, and the two middle members are respectively connected to the two bases and simultaneously connected to the mounting seat.

[0150] The opening of the "V" shape formed among the two bases, the two middle members and one mounting seat is changed to face downward, and the generated acting force can realize the extrusion of the tooth.

[0151] Combined Figure 13 and Figure 14 , it is an application scenario for tooth uprighting correction.

[0152] The force application platform 10d includes two housings 11d, 12d connected to each other. The two housings 11d, 12d include a first housing 11d and a second housing 12d. The first housing 11d includes a window 112d. The connecting member 20d includes two bases 21d, one mounting seat 22d and two middle members 23d.

[0153] The two bases 21d are respectively located in the first housing 11d and the second housing 12d. When the dental system 100d is worn in the oral cavity, the mounting base 22d is directly connected to the tooth at the opening 112d, and the two middle members 23d are respectively connected to the two bases 21d and at the same time connected to the mounting base 22d.

[0154] The first housing 11d includes an extension 111d extending to the gingival area, and the base 21d located in the first housing 11d is located in the extension 111d.

[0155] The two bases 21d and the mounting base 22d are both arranged corresponding to the buccal side of the tooth. The two bases 21d are buckle-shaped structures, and the mounting base 22d is a hook-shaped structure with bidirectional traction, that is, the mounting base 22d has two hooks 221d. The two middle members 23d are respectively sleeved at the two hooks 221d. The middle member 23d is an annular elastic member, that is, there is an elastic connection between the middle member 23d and the base 21d, and there is an elastic connection between the middle member 23d and the mounting base 22d. The two bases 21d are bonded to the force application platform 10d, and the mounting base 22d is bonded to the tooth.

[0156] When the dental system 100d is worn in the oral cavity, the two middle members 23d are deformed to generate a first pulling force F1 and a second pulling force F2 that are inclined with respect to the gingival occlusal surface direction z. The first pulling force F1 is directed towards the upper left, and the second pulling force F2 is directed towards the lower right. The first pulling force F1 and the second pulling force F2 act on the tooth through the mounting base 22d, and the tooth is pulled in two directions to achieve orthoaxial correction.

[0157] Combined Figure 15 and Figure 16 , it is an application scenario for tooth translation correction.

[0158] The force application platform 10e includes two housings 11e, 12e connected to each other. The two housings 11e, 12e include a first housing 11e and a second housing 12e. The first housing 11e includes an opening 112e. The connecting member 20e includes a base 21e, a mounting base 22e and a middle member 23e. The base 21e is located in the first housing 11e.

[0159] When the dental system 100e is worn in the oral cavity, the mounting base 22e is directly connected to the tooth at the opening 112e. The base 21e is located on the distal side of the mounting base 22e, and the middle member 23e extends substantially along the mesiodistal direction x.

[0160] The base 21e and the mounting base 22e are both arranged corresponding to the buccal side of the tooth. The base 21e is a buckle-like structure, the mounting base 22e is a hook-like structure, and the intermediate member 23e is an annular elastic member. That is, there is an elastic connection between the intermediate member 23e and the base 21e, and there is an elastic connection between the intermediate member 23e and the mounting base 22e. The base 21e is bonded to the force application platform 10e, and the mounting base 22e is bonded to the tooth.

[0161] The first housing 11e includes an extension 111e extending to the gingival area, and the base 21e located on the first housing 11e is located on the extension 111e.

[0162] When the dental system 100e is worn in the oral cavity, the intermediate member 23e deforms to generate a pulling force F that is away from the mounting base 22e and is substantially parallel to the mesiodistal direction x. This pulling force F acts on the tooth through the mounting base 22e, thereby achieving the mesial translation of the tooth.

[0163] In other embodiments, the extension direction of the intermediate member 23e may have an acute angle with the mesiodistal direction x. At this time, the component force of the force generated by the intermediate member 23e along the mesiodistal direction x can be used as the pulling force for translational orthodontics.

[0164] When the base is located on the mesial side of the mounting base, the mesial translation of the tooth can be achieved.

[0165] Combined Figure 17 , it is an application scenario for tooth torsion correction.

[0167] When the dental system 100f is worn in the oral cavity, the mounting base 22f is directly connected to the tooth at the window 112f, and the base 21f is located on the mesial side of the mounting base 22f.

[0168] The base 21f and the mounting base 22f are both arranged corresponding to the buccal side of the tooth. The base 21f and the mounting base 22f are both tubular structures or groove-like structures, such as buccal tubes. The intermediate member 23f is a rigid arch wire. There is a rigid connection between the intermediate member 23f and the base 21f, and there is a rigid connection between the intermediate member 23f and the mounting base 22f. The base 21f is bonded to the force application platform 10f, and the mounting base 22f is bonded to the tooth.

[0169] When the dental system 100f is worn in the oral cavity, the intermediate member 23f generates a pulling force, and this pulling force can achieve the torsion of the tooth.

[0170] In summary, the force - applying platform 10 of the present utility model is clamped between the upper teeth T1 and the lower teeth T2, which will not bring additional discomfort to the patient. Moreover, the position of the force - applying platform 10 in the oral cavity is stable at this time, which can effectively increase the anchorage and provide a stable acting force.
